if you are looking to get that stock sound of a bike out of here, this is the way to do it. the duke already sounds different but this adds such a booming sound that taking the db killer out is almost pointless unless you cant hear already, 11/10 would buy again.

Sound: Very loud. Louder than I anticipated. Even at idle this thing transforms the sound of the Duke 390. (Videos do not do it justice)

Fit & Finish: Everything seems high quality and strong. The only issue i had was with the orange bracket. It felt a little flimsy, but this was to allow it to bend when securing it to the exhaust. Had to bend it a little to fit the bolts through the top.

Overall: Great exhaust for the money. If you want something that matches the styling of the 390 Duke and kicks ass in the sound department, then look no further.
